“Clifford the Big Red Dog” began life as a children’s book series, with author Norman Bridwell delighting young readers for decades with his vision for adventure and mischief featuring a gargantuan canine and his bottomless love for his human pal, Emily Elizabeth. There were 80 books dedicated to Clifford’s curiosity and heroism, eventually inspiring a hit animated series with John Ritter as the voice of the eponymous pooch. There’s been a lot of Clifford over the years, and the brand name is newly reenergized by “Clifford the Big Red Dog,” a live-action adaptation of Bridwell’s creation, which brings the character to life through CGI, unleashing his chaos in a family comedy that’s attempting to establish a new direction for all things Clifford.
